It seems to be VERY individual - whether one can learn to get out easy or not, based on experience from those having these suits for a while
I have tried them but even after hours of trying different ways, it does not work at all for me - either impossible (as I am not very flexible), or at least so troublesome to get out of, so I will never have one of these
Getting in/out of the wetsuit easy and fast is my main priority - also the reason I often change from the 3/2 autumn fullsuit and almost directly to the drysuit (at least when I need boots, the wetsuit is out of the question) - and only using the 5/3 fullsuit for maybe one month typically...
As a drysuit is way faster and easier than a 5/3 IMO.
But agree - that non-zip suits ARE more flexible and fits better
Just not usable for me
Different people different likings - some will never get used to non-zip, others have no problems
